Not quite. Torque is the determining factor on engine load, not hp (even though yes, they're closely related). That's why a truck with 300hp would probably have no trouble towing a 3-ton trailer, when you definitely wouldnt try to tow that trailer with a 300hp civic.
An engine with higher torque is always going to handle more load than an engine with lower torque but comparable hp.
My comment was regarding the amount of load caused by the fan. If it draws “30 HP” on one motor it’s going to draw 30 hp on another because of the amount of work it takes to turn the fan stays consistent.
